On this date in 1982, the first compact discs for commercial release were manufactured in Germany. CDs were originally designed to store and play back sound recordings, but later were modified to store data. The first test disc, which was pressed near Hannover, Germany, contained a recording of Richard Strauss's An Alpine Symphony, played by the Berlin Philharmonic. The first CD commercially produced at the new factory and sold on this date was ABBA's 1981 album The Visitors; the first new album to be released on CD was Billy Joel's 52nd Street, which hit the stores in Japan — alongside the new Sony CD player — on October 1. The event is known as the "Big Bang of digital audio."
